Clematis plant ‘GOLDEN DREAM’

ABSTRACT

A new and distinct Clematis hybrid named ‘GOLDEN DREAM’ is disclosed, characterized by yellow flowers with a distinct maroon colored base. Plants begin flowering in Spring and rebloom throughout the Summer. Flowers are pendulous and have a light citrus scent. The new cultivar is a Clematis typically suited for ornamental container and landscape use.

Latin name of the genus and species: Clematis hybrid.

Variety denomination: ‘GOLDEN DREAM’.

BACKGROUND OF THE INVENTION

The new Clematis cultivar is a product of a planned breeding program conducted by the inventor, Szczepan Marczynski, in Pruszkow, Poland. The objective of the breeding program was to produce new compact Clematis varieties with novel or new colors. The cross resulting in this new variety was made during May of 2013.

The seed parent is the unpatented Clematis ‘Lemon Bells’. The pollen parent is the unpatented Clematis ‘Lemon Dream’. The new variety was identified as a potentially interesting selection in Spring of 2014 at a greenhouse in Pruszkow, Poland.

Asexual reproduction of the new cultivar ‘GOLDEN DREAM’ by softwood cuttings was first performed during June of 2015, at a greenhouse in Pruszkow, Poland. Subsequent propagation has shown that the unique features of this cultivar are stable and reproduced true to type in 4 successive generations.

SUMMARY OF THE INVENTION

The cultivar ‘GOLDEN DREAM’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘GOLDEN DREAM.’ These characteristics in combination distinguish ‘GOLDEN DREAM’ as a new and distinct Clematis cultivar:

-   -   1. Yellow flowers with a maroon base.     -   2. Flowering begins in Spring, reblooming occurs throughout the         Summer.     -   3. Flowers have a light citrus scent.     -   4. Pendulous flowers.

PARENTAL COMPARISON

Plants of the new cultivar ‘GOLDEN DREAM’ are similar to plants of the seed parent in most horticultural characteristics however, plants of the new cultivar ‘GOLDEN DREAM’ differ in the following:

-   -   1. Flowers of the new variety are double and semi-double;         flowers of the seed parent are single.     -   2. The new variety produces larger flowers, which have longer         and wider petals than the seed parent.     -   3. Flowers of the new variety have a light citrus fragrance;         flowers of the seed parent have no fragrance.

Plants of the new cultivar ‘GOLDEN DREAM’ are similar to plants of the pollen parent, in most horticultural characteristics, however, plants of the new cultivar ‘GOLDEN DREAM’ differ in the following;

-   -   1. Flowers of the new variety are double and semi-double;         flowers of the pollen parent are entirely double.     -   2. Flowers of the new variety are smaller than flowers of the         pollen parent.     -   3. Flowers of the new variety have a maroon base; flowers of the         pollen parent are solid creamy yellow.     -   4. Petals of the new variety are not as undulating as petals of         the pollen parent.

COMMERCIAL COMPARISON

Plants of the new cultivar ‘GOLDEN DREAM’ can be compared to the known commercial variety Clematis ‘Zocoro’, U.S. Plant Pat. No. 24,642. The Clematis varieties are similar in most horticultural characteristics, including their distinctive pendulous flowers, however, ‘GOLDEN DREAM’ differs from the comparator in the following:

-   -   1. Flowers of ‘Golden Dream’ are yellow and maroon; flowers of         this comparator are pink.     -   2. Flowers of the new variety are completely pendulous, facing         downward; flowers of ‘Zocoro’ face both outwards and downwards.     -   3. Petals of the new variety are wider than petals of this         comparator.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photograph in FIG. 1 illustrates in full a typical plant of ‘Golden Dream’ in a three gallon pot, grown outdoors in Pruszkow, Poland. This plant is approximately 2 years old, grown outdoors.

FIG. 2 illustrates a closer view of typical flowers and foliage of ‘GOLDEN DREAM’.

The photographs were taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.
